DemWAD01 is a single-level PWAD for Doom II, released on 23 August 2010 and updated in October of that year. It was designed by vdgg. The WAD is designed to play back with lv01-039.lmp, the Compet-NUV max record for MAP01 of Doom II, set by Jim Leonard (Xit Vono) in 2006. In this map, the same demo will kill all monsters and successfully exit. Leonard recorded a UV max speedrun especially for the map, beating it six seconds faster. This demo was included with the 1.1 update for the map.
